The liquid heater comprises a steel pipe which is provided with a water inlet and a water outlet, a hollow plastic cylinder is mounted in the steel pipe, a spiral groove is engraved on the outer wall of the plastic cylinder, a water channel is formed between the groove and the inner wall of the steel pipe, and both ends of the water channel are respectively communicated with the water inlet and the water outlet; seal rings are mounted on both ends of the steel pipe; the surface of the steel pipe is covered with an insulating layer, a thick-film resistor circuit is printed on the surface of the insulating layer, and a temperature-controlling unit which is connected with the thick-film resistor circuit is fixed on the steel pipe as well. The spiral water channel which is formed between the steel pipe and the plastic cylinder can prolong the liquid-heating distance, consequently, heating can be more uniform and sufficient, and the temperature of the liquid can be increased faster. Compared with the conventional plate-shaped liquid heater, the liquid heater provided by the utility model is pipe-shaped, and can be mounted in a cramped space such as an electric heating tap, so the liquid heater can be widely applied.
Description
Technical field
The utility model belongs to technical field of water heaters, specially refers to liquid heating.
Background technology
Traditional heating tube is made up of resistance wire, magnesia powder and outside steel pipe, utilizes resistance wire to heat, and magnesia powder heat conduction is final by the steel pipe liquid that heat transferred is to be heated.Its shortcoming is to pass to liquid to be heated via magnesia powder and steel pipe successively after the resistance wire heating, and not only heat conduction velocity is slow, also causes the thermal efficiency low, and service life is short.Occurred the liquid heating of utilizing tabular thick film circuit to make at present, because that this kind heater exists volume is bigger, the heat that water channel absorbs increases, and causes the problem that firing rate is slack-off and energy consumption increases.And be difficult to be installed in the narrow spaces such as electric hot water tap, there is certain limitation in the scope of application.
The utility model content
The purpose of this utility model is to propose a kind of simple in structure, cost is low, heating is effective, flexible for installation liquid heating.
Liquid heating of the present utility model comprises a steel pipe with water inlet and delivery port, hollow plastic barrel is installed in the described steel pipe, the outer wall of described plastic barrel is carved with spiral helicine groove, form tank between the inwall of described groove and steel pipe, the two ends of described tank communicate with water inlet and delivery port respectively; The two ends of steel pipe are equipped with sealing ring; Described steel tube surface is coated with insulating barrier, and the surface of described insulating barrier is printed with the thick-film resistor circuit, also is fixed with the temperature control unit that is connected with described thick-film resistor circuit on the steel pipe.
Form spiral helicine tank between steel pipe and the plastic barrel, can prolong the distance of liquid heating, make heating more even, abundant, the liquid temperature rise speed is faster, confirm that through overtesting temperature rise speed can reach 200～300 degree per seconds, can satisfy the needs of most immediately heating water heaters; Steel pipe directly contacts with liquid to be heated, has reduced heat conducting distance, thereby improves the heat conduction velocity and the thermal efficiency; Sealing ring can prevent the leak of liquid in the steel pipe; Described plastic barrel is hollow, can reduce heat loss, improves the efficiency of heating surface.Compare traditional tabular liquid heating, liquid heating of the present utility model is a tubulose, can be installed in the narrow spaces such as electric hot water tap, and the scope of application is more extensive.
Described thick-film resistor circuit is to be formed by conductive silver paste and the good rare earth resistance slurry sintering of drafting as the lead purposes, and its surface preferably is coated with protective layer, prevents accidental destruction thick-film resistor circuit.
Described protective layer adds fine injection mo(u)lding by nylon, not only protects effectively, and because the heat-conductive characteristic of nylon is poor, therefore can play heat preservation effect, kills two birds with one stone.
Described insulating barrier forms for the glass paste mixture sintering, and its thickness is blocked up can to influence heat-conducting effect, influence insulation effect and cross thin meeting.Through checking, when the thickness of insulating barrier during at 0.05～0.15 millimeter, heat-conducting effect can meet the demands, and its withstand voltage 1500～3700V that reaches, and satisfies insulating requirements.
Described temperature control unit is by thermistor and can disconnect or the control circuit of closed described thick-film resistor circuit be formed according to thermistor signal.This liquid heating just can be applied in water dispenser or the solar water heater like this, when being applied to water dispenser, it can be arranged on the outlet pipeline place, how much water to heat how much water with as required, avoid boiled water all not drunk, solve traditional water dispenser repeated boiling and produce thousand boiling water harmonizing yinyang water phenomenons; When being applied to solar water heater, can be installed on hot water tap place, the water of solar water heater interior conduit is heated, and need not the cold water of this part is bled off, by the time after the hot water in the storage tank was released, control circuit promptly disconnected described thick-film resistor circuit, stopped heating.
The wall thickness of described plastic barrel is 1～1.5 millimeter, and wall thickness is blocked up can to influence the efficiency of heating surface, and crossing thin meeting influence structural strength.
Liquid heating of the present utility model is simple in structure, firing rate is fast, and is flexible for installation, applied widely.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of liquid heating of the present utility model.
The specific embodiment
Describe the utility model in detail below in conjunction with specific embodiments and the drawings.
Embodiment 1:
As shown in Figure 1, the liquid heating of present embodiment comprises a steel pipe 3 with water inlet 1 and delivery port 2, wall thickness be installed be 1 millimeter hollow plastic barrel 4 in the steel pipe 3, the outer wall of plastic barrel 4 is carved with spiral helicine groove, form tank 4 between the inwall of groove and steel pipe 3, the two ends of tank 4 communicate with water inlet 1 and delivery port 2 respectively; The two ends of steel pipe 3 are equipped with sealing ring 6; Steel pipe 3 surface coverage have insulating barrier 7, and insulating barrier 7 forms for the glass paste mixture sintering, and its thickness is 1 millimeter; The surface of insulating barrier 7 forms thick-film resistor circuit 8 by conductive silver paste and the good rare earth resistance slurry sintering of drafting as the lead purposes, also is fixed with the temperature control unit 9 that is connected with thick-film resistor circuit 8 on the steel pipe 3; The thick-film resistor circuit surface preferably is coated with the protective layer 10 that is added fine injection mo(u)lding by nylon.
Temperature control unit 9 is by thermistor and can disconnect or the control circuit of closed resistance silk circuit be formed according to thermistor signal, can disconnect or closed thick film resistance circuit 8 according to the fluid temperature in the steel pipe 3, thereby the control heating, thereby can make this liquid heating be applied to water dispenser or solar water heater product.Protective layer 10 not only can play the effect of protection thick-film resistor circuit 8 and temperature control unit 9, and can play heat preservation effect, kills two birds with one stone.
Liquid to be heated is after water inlet 1 enters, flow in tank 5, because the one side of tank 5 is steel pipe 3 inwalls, so the heat that thick-film resistor circuit 8 produces can heat to liquid to be heated through steel pipe walls, firing rate is very fast, and the liquid after the heating is flowed out by delivery port 2 at last.
The aforesaid liquid heater is simple in structure, firing rate is fast, and is flexible for installation, applied widely.
